Air Delivery Improper

CIRCUIT DESCRIPTION
The heater and A/C programmer will direct the blended air in one of several air delivery modes. The side window outlets receive the airflow during all of the modes of the operation. The heater and A/C programmer directs air to the other outlets by energizing specific vacuum valves. This feeds the appropriate combination of mode valve actuators.

The heater and A/C programmer determines the proper air delivery mode based upon the following factors:
^ Current program number
^ Control panel setting
^ Set temperature
^ Low side temperature
^ Coolant temperature
^ Ambient air temperature
^ Sun load
